Figure 19 is the diagram of curves that the unusual judgment standard of car speed in the storage part 113 that is stored in Figure 18 is shown.In the drawings, the lifting interval of the car 3 in hoistway 1 is provided with in (interval between end layer and the other end layer): the acceleration and deceleration interval makes car 3 carry out acceleration and deceleration near one and another end layer; And the constant speed interval, car 3 is moved with constant speed between each acceleration and deceleration interval.
In the unusual judgment standard of car speed, correspondingly with the position of car 3 be set with 3 grades of detecting patterns.That is, in the unusual judgment standard of car speed, the position with car 3 is set with accordingly respectively: normal speed detecting pattern (normal level) 115, the speed of the car 3 when being normal operation; The 1st abnormal speed detecting pattern (the 1st unusual rank) 116 has the value bigger than normal speed detecting pattern 115; And the 2nd abnormal speed detecting pattern (the 2nd unusual rank) 117, have the value bigger than the 1st abnormal speed detecting pattern 116.

Figure 20 is the diagram of curves that the unusual judgment standard of car acceleration/accel in the storage part 113 that is stored in Figure 18 is shown.In the drawings, in the unusual judgment standard of car acceleration/accel, be set with 3 grades of detecting patterns accordingly with the position of car 3.That is, in the unusual judgment standard of car acceleration/accel, the position with car 3 is set with accordingly respectively: normal acceleration detecting pattern (normal level) 118, the acceleration/accel of the car 3 when being normal operation; The 1st unusual acceleration detection pattern (the 1st unusual rank) 119 has the value bigger than normal acceleration detecting pattern 118; And the 2nd unusual acceleration detection pattern (the 2nd unusual rank) 120, have the value bigger than the 1st unusual acceleration detection pattern 119.
Normal acceleration detecting pattern the 118, the 1st unusual acceleration detection pattern 119 and the 2nd unusual acceleration detection pattern 120 are set for respectively in that constant speed is interval and are null value, in an acceleration and deceleration interval be on the occasion of, be negative value in another acceleration and deceleration interval.And the difference poor and the 2nd unusual acceleration detection pattern 120 and the 1st unusual acceleration detection pattern 119 of the 1st unusual acceleration detection pattern 119 and normal acceleration detecting pattern 118 is not set all the position constants in the lifting interval for.
Promptly, in storage part 113, store normal speed detecting pattern the 115, the 1st abnormal speed detecting pattern 116 and the 2nd abnormal speed detecting pattern 117 as the unusual judgment standard of car speed, store normal acceleration detecting pattern the 118, the 1st unusual acceleration detection pattern 119 and the 2nd unusual acceleration detection pattern 120 as the unusual judgment standard of car acceleration/accel.
When the speed of car 3 surpassed the 1st abnormal speed detecting pattern 116, perhaps when the acceleration/accel of car 3 surpassed the 1st unusual acceleration detection pattern 119, efferent 114 outputed to towing machine usefulness brake equipment 106 to cranking signal (energizing signal).And efferent 114 outputs to control panel 102 to the danger signal that is used to stop to drive towing machine 101 cranking signal being outputed to towing machine with in the brake equipment 106.And when the speed of car 3 surpassed the 2nd abnormal speed detecting pattern 117, perhaps when the acceleration/accel of car 3 surpassed the 2nd unusual acceleration detection pattern 120, efferent 114 outputed to towing machine usefulness brake equipment 106 and emergency braking device 33 to cranking signal.That is, efferent 114 is according to the speed of car 3 and the intensity of anomaly of acceleration/accel, and the brake unit of cranking signal is exported in decision.
Other structures are identical with embodiment 2.
Below, action is described.When from the position detection signal of car position sensor 109, when being imported into efferent 114 from the speed detection signal of car speed sensor 110 and from the acceleration detection signal of car acceleration pick-up 111, at efferent 114, according to the input of each detection signal, calculate position, speed and the acceleration/accel of car 3.Afterwards, at efferent 114, the unusual judgment standard of the car speed that obtains respectively from storage part 113 and the unusual judgment standard of car acceleration/accel speed and the acceleration/accel with the car 3 of calculating according to the input of each detection signal compared, the speed and the acceleration/accel of car 3 each had no abnormal the detection.
When normal operation, because the speed of car 3 has the value roughly the same with the normal speed detecting pattern, and the acceleration/accel of car 3 has the value roughly the same with the normal acceleration detecting pattern, thereby at efferent 114, the speed and the acceleration/accel that detect car 3 are not unusual separately, continue the normal operation of elevator.
In the velocity anomaly rising that for example makes car 3 for a certain reason and above under the situation of the 1st abnormal speed detecting pattern 116, the speed that detects car 3 at efferent 114 has unusually, cranking signal is output to towing machine brake equipment 106 from efferent 114, and danger signal is output to control panel 102 from efferent 114.Like this, towing machine 101 is stopped, and make towing machine, the rotation that drives rope sheave 104 is braked with brake equipment 106 startings.
And, surpass under the situation of the 1st unusual acceleration/accel setting value 119 in the acceleration/accel abnormal ascending of car 3, cranking signal and danger signal are output to towing machine respectively with brake equipment 106 and control panel 102 from efferent 114, and the rotation that drives rope sheave 104 is braked.
After towing machine is with brake equipment 106 startings, in the further rising of the speed of car 3 and above under the situation of the 2nd abnormal speed setting value 117, cranking signal outputed to towing machine with under the state of brake equipment 106 keeping, cranking signal is output to emergency braking device 33 from efferent 114.Like this, make emergency braking device 33 starting, car 3 is braked by the action identical with embodiment 2.
And, after towing machine is with brake equipment 106 startings, in the further rising of the acceleration/accel of car 3 and above under the situation of the 2nd unusual acceleration/accel setting value 120, cranking signal outputed to towing machine with under the state of brake equipment 106 keeping, cranking signal is outputed to emergency braking device 33 from efferent 114, make emergency braking device 33 startings.
In this lift appliance, because monitor unit 108 is obtained the speed of car 3 and the acceleration/accel of car 3 according to the information from the detecting unit 112 that the elevator state is detected, when any one party in the acceleration/accel of the speed of judging obtained car 3 and car 3 is unusual, cranking signal is outputed to towing machine with at least any one party in brake equipment 106 and the emergency braking device 33, thereby, the detection that can make 108 pairs of abnormal elevators of monitor unit more early and more reliable can further be shortened from abnormal elevator taking place to producing the time required to the braking force of car 3.Promptly, because the speed of car 3 and the so multiple unusual judgement key element of acceleration/accel of car 3 have no abnormal by monitor unit 108 judgement separately respectively, thereby, the detection that can make 108 pairs of abnormal elevators of monitor unit more early and more reliable can be shortened from abnormal elevator taking place to producing the time required to the braking force of car 3.
And, because monitor unit 108 has storage part 113, this storage part 113 stores and is used to judge that the speed of car 3 has the unusual judgment standard of N/R car speed and is used to judge that the acceleration/accel of car 3 has the unusual judgment standard of N/R car acceleration/accel, thereby, the speed and the acceleration/accel that can easily change car 3 each have N/R judgment standard, can easily tackle the design modification of elevator etc.
And, owing in the unusual judgment standard of car speed, be set with: normal speed detecting pattern 115; The 1st abnormal speed detecting pattern 116 has the value bigger than normal speed detecting pattern 115; And the 2nd abnormal speed detecting pattern 117, have the value bigger than the 1st abnormal speed detecting pattern 116, when the speed of car 3 surpasses the 1st abnormal speed detecting pattern 116, cranking signal is output to towing machine brake equipment 106 from monitor unit 108, when the speed of car 3 surpasses the 2nd abnormal speed detecting pattern 117, cranking signal is output to towing machine brake equipment 106 and emergency braking device 33 from monitor unit 108, thereby, can carry out the stage braking to car 3 according to the velocity anomaly size of car 3.Therefore, can reduce the frequency that applies large impact to car 3, and car 3 is stopped more reliably.
And, owing in the unusual judgment standard of car acceleration/accel, be set with: normal acceleration detecting pattern 118; The 1st unusual acceleration detection pattern 119 has the value bigger than normal acceleration detecting pattern 118; And the 2nd unusual acceleration detection pattern 120, have the value bigger than the 1st unusual acceleration detection pattern 119, when the acceleration/accel of car 3 surpasses the 1st unusual acceleration detection pattern 119, cranking signal is output to towing machine brake equipment 106 from monitor unit 108, when the acceleration/accel of car 3 surpasses the 2nd unusual acceleration detection pattern 120, cranking signal is output to towing machine brake equipment 106 and emergency braking device 33 from monitor unit 108, thereby, can carry out the stage braking to car 3 according to the acceleration/accel of car 3 is big or small unusually.Usually, because before the speed of car 3 took place unusually, the acceleration/accel of car 3 took place unusual, thereby can further reduce the frequency that applies large impact to car 3, and car 3 is stopped more reliably.
And, owing to be set with normal speed detecting pattern the 115, the 1st abnormal speed detecting pattern 116 and the 2nd abnormal speed detecting pattern 117 accordingly with the position of car 3, thereby, can set the 1st abnormal speed detecting pattern 116 and the 2nd abnormal speed detecting pattern 117 accordingly respectively at all positions and the normal speed detecting pattern 115 in the lifting interval of car 3.Therefore, because particularly in the acceleration and deceleration interval, the value of normal speed detecting pattern 115 is little, thereby, can set the 1st abnormal speed detecting pattern 116 and the 2nd abnormal speed detecting pattern 117 for smaller value respectively, can reduce the impact that causes by braking car 3.
In addition, in above-mentioned example, obtain the speed of car 3 for making monitor unit 108, used car speed sensor 110, yet also can not use car speed sensor 110, and according to the speed that derives car 3 by the position of car position sensor 109 detected cars 3.That is, also can obtain the speed of car 3 by to differentiating according to the position of the car 3 of calculating from the position detection signal of car position sensor 109.

Figure 34 is the instruction diagram that is illustrated in the normal mode of the process information that is write in the RAM203 of Figure 31.In this embodiment, 1～7 discre value is assigned to 7 calculation process, at cooresponding TBL[0]～write discre value in [6].TBL[7]～[9] in owing to there is not cooresponding calculation process, so still be 0.
If the pattern of process information is normal, then as shown in figure 35, TBL[0]～the storage pointer of [9] and table is initialized to 0 (step S7).Afterwards, carry out in turn the needed signal of input computing input computing (step S8), obtain the current location of car car position computing (step S9), detect have or not the calling scan operation (step S10) of calling out login, obtain from the current location of car to the distance of destination layer distance operation (step S11) and according to the operating instruction computing (step S12) of the operating instruction of obtaining car to the distance of destination layer.
When carrying out the operating instruction computing, carry out the monitoring device computing (step S13) that is used for the elevator state is carried out the monitoring device demonstration.At last, execution is used to export the output computing (step S14) that makes the needed command signal of cage operation.
And, after having carried out each computing, carry out that discre value is written to processing (step S15～21) in the corresponding tables at once.That is, alternately carry out calculation process and discre value writes.
Specifically, after the input computing of having carried out as initial computing, at once at TBL[P] in write 1, make storage pointer P add 1 (step S15).Then, after having carried out the car position computing, at once at TBL[P] in write 2, make storage pointer P add 1 (step S16).Carry out such processing in turn, after the output computing of having carried out as last computing, at once at TBL[6] in write 7.
The pattern of the discre value that is write interrupts being identified when computing begins (step S6) at the next one like this.If the execution sequence of calculation process is normal, then the pattern of discre value as shown in figure 34.And if the order mal of calculation process, perhaps when once interrupting repeating identical calculation process in the execution cycle, then the pattern of discre value is different with Figure 34, detects unusually by control setup main body 206.
When the execution sequence that detects calculation process is unusual, carry out the computing (step S22) that car is promptly stopped.And, under the unusual situation of the execution sequence that detects calculation process, send anomaly detection signal to the elevator monitoring chamber.When execution promptly stopped computing, execution monitoring device computing (step S23) was carried out output computing (step S24), the end interrupt calculation process.
In such elevator control gear, execution sequence unusual of calculation process can be detected rapidly, thereby the computing relevant that uses a computer and carry out can be carried out reliably with s operation control, can improve reliability.And, also can detect and cause such unusual of self-loopa by program exception.
Here, be difficult to find out the unusual reason of the execution sequence of calculation process, fault restoration is very time-consuming.Execution sequence unusual of calculation process also takes place because of microcomputer or program unusual sometimes, yet if they are not unusual, most probable reason is considered to interrupt computing and does not finish (operation time is overtime) in the time at execution cycle.
Usually it is overtime that can not take place operation time, calls out scan operation and need under the situation such as long-time yet for example made by multi-pass operation at call button, because that take place operation time in interim increase operation time is overtime.And, think owing to the transformation of carrying out software repeatedly and improvement etc. make increase gradually operation time, also cause the generation that operation time is overtime.
Relatively,, can more early detect execution sequence unusual of calculation process, can improve reliability to the preventing trouble before it happens of secondary failure according to the elevator control gear of embodiment 17.
And,, can further improve reliability because control setup main body 206 is just confirmed the pattern of process information every predefined execution cycle, thereby can often monitor unusual having or not.
And, owing to have when unusual, car is promptly stopped, thereby can prevent to become bigger fault at the execution sequence that is judged as calculation process.
Then, Figure 36 is the diagram of circuit of flow process that the interruption computing of 18 elevator control gear is shown according to the embodiment of the present invention.In this embodiment, be under the normal situation at the execution sequence of calculation process, carry out the calculation process (step S7～21) identical with embodiment 17.On the other hand, under the execution sequence that is judged as calculation process is unusual situation, carry out input computing (step S25) and car position computing (step S26), carry out afterwards and be used to make car to stop at nearest layer computing (step S27).
Stop under the situation of computing having carried out nearest layer, carry out operating instruction computing (step S28), output makes cage operation arrive the needed command signal of nearest layer.Afterwards, execution monitoring device computing (step S23) and output computing (step S24).
According to such elevator control gear, under the execution sequence that is judged as calculation process is unusual situation, because car is stopped after moving to nearest layer, thereby can make the passenger in the car drop to stop smoothly.
Then, Figure 37 is the diagram of circuit of flow process that the interruption computing of 19 elevator control gear is shown according to the embodiment of the present invention.In this embodiment, be under the normal situation at the execution sequence of calculation process, carry out the calculation process (step S7～21) identical with embodiment 17.On the other hand, under the execution sequence that is judged as calculation process is unusual situation, omit the part of computing performed under the normal circumstances, only carry out needed MIN computing to remain in operation.That is, in this embodiment, omit and call out scan operation and monitoring device computing, and carry out input computing (step S25), car position computing (step S26), distance operation (step S29), operating instruction computing (step S28) and output computing (step S24).
In addition, if detecting the still unsettled layer that sets the goal of the unusual moment, then nearest layer is set at destination layer.
According to such elevator control gear, under the execution sequence that is judged as calculation process is unusual situation,, can guarantee needed MIN operation time by omitting a part of computing, the running of car is continued.
Then, Figure 38 is the diagram of circuit of flow process that the interruption computing of 20 elevator control gear is shown according to the embodiment of the present invention.In this embodiment, be under the normal situation at the execution sequence of calculation process, carry out the calculation process (step S7～21) identical with embodiment 17.On the other hand, under the execution sequence that is judged as calculation process is unusual situation, carries out and promptly stop computing (step S22), and the operative condition of the elevator of this moment is recorded as history (historical computing) (step S31).History is recorded in the predefined zone in the RAM203 for example.After historical computing, execution monitoring device computing (step S23) and output computing (step S24).
Figure 39 is the instruction diagram that illustrates by the historical computing recorded data example of Figure 38.As the operative condition that history write down for example comprise CNT value, date, operation/halted state, service direction, starting layer, as anterior layer, destination layer, calls, TBL[0]～[9] etc.And, once be registered as TIME data (historical data) unusually.And the TIME data are saved (TIME[0]～[15]) 16 times, when surpassing 16 times, preserve up-to-date TIME data, and delete the oldest TIME data.
In addition, the CNT value is to be used to generate each execution to interrupt the data that computing just increases progressively, and according to calculating the value that the unusual generation of calculation process order is used constantly with the difference of checking CNT value constantly.
Figure 40 is the diagram of circuit of flow process that the historical computing of Figure 38 is shown.In historical computing, calculate historical storage address (step S32) according to POINT and BUF, the data (step S33) of the operative condition of storage elevator are upgraded POINT for historical with (step S34) subsequently.Afterwards, confirm whether POINT has reached 16 (step S35), if do not reach then finish historical computing.And, in case POINT has reached 16, just the POINT of historical usefulness is subsequently reverted to 0 (step S36), finish historical computing afterwards.
In such elevator control gear, because the TIME data that the calculation process execution sequence takes place when unusual are saved, thereby, can perhaps help the reason of finding out that generation is unusual to unusual the preventing trouble before it happens of control setup by for example when the maintenance inspection of elevator, confirming the TIME data.And,, can shorten fault correction time by when taking place unusually, confirming the TIME data.
In addition, the historical data that is write down in historical computing is not limited to above-mentioned example.Wherein, as historical data, preferably use the combination of pattern of operation/halted state, service direction, starting layer, any one data at least in the data of anterior layer, destination layer and calls and the process information of car.
